O2 sensor replacement question
The O2 sensor has never been replaced in my '89 3.2L. It currently has about 85K miles and the PO did not have it replaced during the 60K service as specified in the owner's manual.
The car does not exibit any of the problems associated with a faulty sensor. Is this one of those "leave it alone if it's not broken" items or is it worth doing from a preventative maintenace perspective? Its an expensive part, otherwise I would replace it without raising the question.
